Stack #4631041

QuestionAnswer
what is the input phosphor made of cesium iodide
what is the output phosphor made of zinc cadmium sulfide
what is the normal size of the input phosphor ? mag 1? mag2? 25cm, 17cm, 12cm
what is the normal size of the output phosphor 1-2.5
what is the fluoro table made of carbon fiber, polycarbonate..
how do you find the magnification factor input 1 / input 2
how do you find the flux gain output phosphor/input phosphor
how do you find minification input phosphor squared / output phosphor squared
how do we calculate brightness gain minification x flux gain
what happens to exposure when the grid is off center decrease exposure to the entire image
what happens to the exposure when the grid is off level decrease exposure of the entire image
what is the sequence from the input phosphor to the output phosphor xrays-light-electrons-light
if you have something off focus from the grid decreased exposure around the edges
when the grid is inverted or upside down what happens to the image / exposure severe decrease at the edges of the exposure- the image in the center will be good but the edges will appear blank
AEC allows for images to fall within an acceptable range on a _ _ of patients mixed population
the backup timer should not be higher than _ % of anticipated exposure 150%
what is the purpose of the back-up timer if the AEC fails the backup timer will ensure that the patient is not contually being exposed
what is the drawback to AEC technologist must have precise patient positioning
what are the two main radiation productions bremsstrahlung and characteristic
bremsstrahlung makes what time of spectrum continuous energy spectrum
greatest quantity of bremsstrahlung xrays are made at _ of the set kvp 1/3 example: set 120, greatest is at 40
bremsstrahlung: incoming electrons _ _ in the target atom slow around
characteristic xrays are what type of spectrum discrete emmision spectrum
innnermost shell of the atom is k shell
